salinity spiked to 1.029 from 1.024
 
I am giving a water change should I try to lower the salinity during this water change? or over the course of a day or two???

I would do it slowly over a day or two. You don't want to stress anything out byu doing it too fast :wink:

How did it "spike" so high?

Nano 11-11-2011 08:02 PM

I dont know! lol evaporation perhaps? I could have made a mistake too though I am new... I have done a 25 percent water change and lowered it to 1.027 tomorrow I will try to get it back to 1.025 does this sound good?

Any chance your adding salt into your top offs?

What size is your tank? That's quite the increase.

Wayne 11-11-2011 08:06 PM

How are you checking your salinity? What size of tank do you have to have that big of a salinity swing.

Nano 11-11-2011 08:10 PM

its only 20 gallons and The last top off I did I saw there was evaporation so I figured the full dose of sat was not required in fact I did less then half! I use a hydrometer by instant ocean. Should I just be adding fresh water for top offs? or very very mild amount of salt water? again guys I am new so I am making cllassic mistakes I'm sure

When topping up your tank due to evaporation only use RO. No need to add any salt at all since the salt does not evaporate.

ok thanks I will do this in the future! Again sorry you guys I didnt know and thats why I'm here!

One thing I learned when using my coralife hydrometer is that if I didn't rinse it out with freshwater everytime I used it, salt residue and bubbles would cause inaccurate readings (Learned the hard way) I have since got a refractometer because of better accuracy.
